CARGO-HANDLING arraaa'rus.

Application filed October 25, 1919. Serial No. 333,359.

To all whom, it may concern:

Be it known that I, VARREN TRAVELL, citizen of the 'United'States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Cargo- Handling Apparatus, of which the follow ing is a specification.

This invention relates to improvements in cargo handling apparatus. It has been customary in American practice that the building called a freight'shed on a pier stands close to the edge and occupies practically the entire width of the pier. In changing such a' pierto adapt it to cargo handling machinery as at present known, it is necessary to tear down both the shed and the pier, and to rebuild, in order to accommodate and to support the larger loads imposed by cargo cranes of the common Such cranes are commonly of electric locomotive crane type, with a swing ing boom at the edge of the pier outside of the shed, resting inpart on the edge of the roof and covering the marginal space between shed and water, with the boom projecting over the ship and then swinging around in the arc of a circle to a position where they may deposit their loads on the marginal strip of pier. Goods thus deposited alongside the shed then have to be conveyed by hand trucks or other means to whatever part of the shed they are to occupy. If any goods from the ship are to be put directly into a barge or other transhipping bottom on the other side of the pier they have to be again lifted, by another crane, and swung out over the edge, except in cases where the barge can be moored on the stream side of the ship. Pier sheds as commonly existing in this country are not sufiiciently strong to support such cranes, nor is there room therefor, between the pier shed and pier edge, nor sufficient strength in the pier outside of the pier shed. It is an object of the present invention to make a cargo handling apparatus which shall both provide an apparatus which is an improvement over that above described, and also be able to utilize such existing structures. This is accomplished by providing a gantry or framework spanning the roof of the pier shed at a' suitable height above it, carrying a track for a hoisting carnage across it from edge to edge of the pier and provided with.

booms extensible over the water in the direction of the length of the track. This is isting pier. The only requisite change in I the building is the cutting of hatches through substantially the whole of its roof. By this arrangement, a ship alongside can be unloaded at any point by running the gantry boom out over her and then, by the hoist and transporting carriage and way, lifting goods therefrom" and running them to any desired position across the width of the pier I shed for'lowering through a'hatch uncovered for the purpose, or running them acrossto and out upon the boom extended at the other side of the pier and thence into a barge alongside the pier. If it be desired to carry the goods lengthwise of the pier, that can be done by moving the gantry structure while the load is suspendedg-or the load can be shifted at any place across the width of the pier to an interior conveyance. The major part ofthe unloading can ordinarily be done by direct hoist, horizontal transport and-deposit to final position, the hoist and carriage operating at high speed, as compared with the slow swinging of a boom to the margin of the pier shed as in the wharf cranes now common; The full width of the shed is as available as is the nearer margin;

and the wall of the shed can be close to the shall cover, by suitable expression in the.

appended claim, whatever features of patentable novelty exist in the invention disclosed.

In the accompanying drawing; the figure is an end elevation in section through a pier embodying the invention.

Referring to the drawings, 10 indicates the floor or level of a pier supported on piles 11 and having a pier house or shed 12 with a roof 13. This represents an exist.

ing pier to which the invention is to be applied, by considering that the piling structure 11 extends only as indicated by the dimension line a in the drawing. This would be in accordance with common practice, there being but a narrow margin outside of the walls of the pier house, and the pilingbeing adequate only for that with its load. The piles b at each edge of the structure illustrated are added forthe purposes of the invention, to carry the extra stresses resulting from the singlera'il of track carrying the overhead transverse way and boom. However, they are not enough to carry that track alone. They are set rather close together and are at the top tied together with the existing closely set marginal piles and with the other piles across the full width of the pier; and by this cooper ation a re1a-v tively minor addition to the width of the pier is suflicient to form roomand a firm marginal support for a single line of rails 14, one at each edge of the pier, on which run wheels 15 supporting a gantry or framework having a trussed leg structure 16 rising to above the level of the roof, and there supporting the trussed bridge or framework 17 which carries the way on which the earriage 19 runs transversely of the pier t 11 3) distance across it, or out on a boom on the other side. This is illustrated in position ove-ra barge 20 on the Side of the pier opposite the ship 21 whichis being loaded or unloaded. The carriage 19 is illustrated as being supported by a boom 22 which is extensible the direction of its own length. Such a boom and carriage may be constructed and operated as de scribed in my U.. Letters Patent No. ,63 e tled, 01 1, da d J 1 1 the carriage running either on the boom or on a. stationary way carried on the trussed the figure, inward ove the boom andupon the permanent way as far as the rope. which holds it runs, whlch may be either to a sheave atsome point on the permanent way, 1 or to asheave at the outward extremity of the other b00111, as can be understood from my said patent; so that both carriages 19 can operate from the end of one boom totheother in case that is desirable; or can operate separately on theirrespective booms.

I claim as my invention: J The combination, with a complete, operatiVe pier comprising a piling structure with floor and house in and over water, said house being close to the water edge 9f the pier, of additional narrow piling structures extending along said house on both water margins of the first mentioned piling structure, tied thereto and supported thereby; and gantry crane supported by said marginal piling structures, bridging over the said house and cooperating therewith I through epenings in its root.
